We have seen the speed torque characteristic of the machine. In the stable region of operation in the motoring mode, the curve is rather steep and goes from zero torque at synchronous speed to the stall torque at a value of slip s = ŝ. Normally ŝ may be such that stall torque is about three times that of the rated operating torque of the machine, and hence may be about 0.3 or less. This means t...

A plant can track an input command signal if it is driven by a controller whose transfer function approximates the inverse of its transfer function. A stable inverse can be obtained even if the plant is nonminimum-phase. No direct feedback is used, except that the plant output is monitored and utilized to adapt the parameters of the controller. A model-reference inverse control system can learn...

The ITER plasma control system has the same functional scope as the control systems in present tokamaks. These are plasma operation scenario sequencing, plasma basic control (magnetic and kinetic), plasma advanced control (control of RWMs, NTMs, ELMs, error fields, etc) and plasma fast shutdown. This chapter considers only plasma initiation and plasma basic control. This chapter describes the p...

The injector Linac control system for SPring-8 is under development and the first trial will be held soon for testing total performance. We designed this system using object oriented methodology to integrate the operator environment and the database architecture and for easy maintainability. A disadvantage of the object oriented approach is a long lead time for abstraction, modeling and definit...

Interferons (IFNs) are secreted cytokines with the ability to activate expression of IFN stimulated genes that increase resistance cells virus infections. Activated transcription factors in conjunction chromatin remodelers induce epigenetic changes reprogram responses. Unexpectedly, 8-oxoguanine DNA glycosylase1 (Ogg1) knockout mice show enhanced stimuli-driven confers increased viral and bacte...
